Thank you for finding this information, and for taking the time to help me. Seems like a logical connection.
I am not sure WHEN the oak leaves were carved. This is a large older stone in a family plot, with (I believe) all of the names of those buried there on it. The oldest/longest lived is the person who died most recently (1830-1907). The others are grown children, and two spouses. I am guessing that the names and dates were carved after each passed away, but am not even sure when the stone was made (when the first passed away, or sometime later).
